... the current check-once-a-week / put-up-an-alert-on-startup approach to justify all of that work.
Good idea but surprisingly tricky to implement - not only would we have to add code to support remote notifications, we'd also have to keep track of which devices had which dictionaries installed on them and only deliver notifications to the devices that need them. So I don't know if it would offer enough benefit over the current check-once-a-week / put-up-an-alert-on-startup approach to justify all of that work.
That's only been out for about 2 days, so it makes sense it wouldn't have notified you yet.
